GOGGLES Filed Feb. 25, 1937 INVENTQR Char/es F/scher ATTORNEY Patented July 5, 1938 UNITED STATES PATENT OFFICE 4 Claims.

The invention relates to improvements in goggles and has particularly to do with that type of goggles used by aviators, drivers of racing automobiles, motor boats or any other apparatus where a high speed is maintained.

The present invention has to do with goggle pads and the means for securing the goggle pads in position;

` One of the objects of the invention is to provide a goggle pad formed to closely and comfortably t any face, and which is adapted, in use, to prevent the entry of excess air currents, dirt and other substances to the interior of the goggle.

A further object is the provision of a simple arrangement whereby the goggle pad may be easily and quickly inserted in or removed from the goggle frame.

This application is a reling in part of my abandoned application Serial No. 622,200, filed July 13, 1932.

Other objects and advantages will become apparent as this specification proceeds. Referring to the drawing forming a part thereof:

Fig. 1 is a front elevation of the goggle embodying the improvements of the present invention;

Fig. 2 is a cross-sectional view taken online 2'2 of Fig. 1;

Fig. 3'is an enlarged detail sectional View taken in the same plane as Fig. 2;

Fig. 4 is a fragmentary elevation showing the goggle pad removed from the frame;

Fig. 5 is asectional view of the goggle pad, onehalf thereof being shown with the retaining ring attached and the other half without the retaining` ring;

Fig. 6 is a fragmentary side elevation showing a portion of the frame and the clamp for opening and closing same to permit the removal or 4 insertion of the goggle pad;

Fig. 7 is a detail view showing the rear face of the slide forming part of the clamping arrangement;

Fig. 8 is a fragmentary view in elevation looking at right angles to Fig. 6; and

Fig. 9 is a detail horizontal sectional view of the clamping arrangement.

The pad I0 is formed of a material such as soft rubber and is, preferably, molded in dish form with its lower edge, at the central region, recessed in inverted U-shape at' II, to fit about the nose of the wearer. 'I'he pad has a central portion or bridge I2 separating a pair of eye openings I3. The eye openings are surrounnded by what is termed peripheral flanges I4, the purpose of which will hereinafter be described.

A retaining ring I5', particularly shown in Figs. 2, 3, 4 and 5, is provided for each eye opening and the pad or the peripheral flange I4 about each eye opening is shaped similar to the shape of the rings. Each ring is composed of light metal, such as aluminum and the cross-section thereof may be of various shapes. A half-round cross-section is illustrated and this is preferred as it avoids sharp edges and provides a round exterior surface adapted to closely fit a cooperating groove in each frame, as will be hereinafter described. It also provides a iat interior surface which is readily adapted to rest against the peripheral flange I4 formed about each eye opening.

Preferably, each ring is circumferentially grooved as indicated at I6 and is formed with a series of openings in each groove for the passage of thread' I1 for binding the rings to the pad about the eye openings. With this arrangement, the rings can be secured to the pad and the binding thread will be concealed and will not contact with the surfaces of the lgrooves in the frame member.

In accordance with the invention the initial area of each eye opening in the pad is less than the area enclosed by each ring I5, and the rings and pad are assembled together by spreading the pad to enlarge the openings and fit them to the f rings. When this is done the peripheral flange I4 about each eye opening is brought into contact with the flat surface of one of the rings I5 and the binding thread I'I is passed through each ange and the series of openings in the groove of each ring to securely fasten the pad and rings together.

When the eye openings I3 are spread and enlarged, the outer portions of the pad curl downwardly and inwardly. This effects a considerable increase in the curvature of the pad and it assumes the form of a pair of cups. This is particularly illustrated in Fig. 5, the left-hand side showing one-half of the pad in dish form before the ring is attached to the eye opening, and the right-hand side showing the other half of the pad in cup form, after the eye opening has been enlarged, tted and bound to its retaining ring,

the latter being adapted to maintain the in- L presses the pad tightly against the face of the wearer and effectively prevents the entry of forceful air currents, rain, dirt or other substances, which might effect the vision and safety of the iiight.

Deterioration of the rubber pad, which might becaused by perspiration, may be avoided by cementing a lining, such as chamois, to the interior of the pad.

As shown, a single, one-piece frame 20 is provided for each eye opening. The frames are hinged together at 2| and provided with lenses 22. Each frame is formed with a bead 23 which forms a rounded interior groove adapted to closely t over the previously-described exterior curved surface of one of the rings. This provides a simple and effective means for seating the rings and securely attaching them in position about the eye openings of the goggle.

Each frame has a straight inner side adapted to carry the hinge connection and from this straight inner side is curved, slopes outwardly and increases in Width. At the outer, widest portion each frame is open, or transversely split and is provided with clamping means 25 for normally holding the edges of the frame along the opening in abutting engagement. The clamping means is operable to release the frame edges from abutting relation and permit the frame to open for insertion or removal of the goggle pad and lens member.

The clamping arrangement is particularly illustrated in Figs. 6, 7, 8 and 9 and comprises a slide 26 which is tapered and turned under along each side to provide a pair of channels 21 adapted to receive and slide on Wings 28, formed by reversely bending a portion of the frame along each edge at the opening in the frame. At one end the slide is formed With a nose 29, perforated at 30 and adapted to receive and hold perforated ears 3| on the frame, one ear being provided at each side of the opening in the frame. The ears 3| may be separate parts riveted to the frame, or, as preferred, can be made integral with the frame. The end of the slide, opposite the nose 29, is angularly disposed to the slide and this end 32 acts as a stop, which engages the frame when the clamping means is closed. Adjacent the stop 32 the slide is provided with a nger-piece 33 in the form of a protuberance, for aiding in the removal of the slide.

The rings 35 of the head band pass through the openings in the nose of the slide and in the ears 3| When these openings are in alignment. It is thus impossible for the slide to be removed when the head bands are attached.

It will be understood that, in carrying the invention into practice, changes may be made in the improvements, described, without departing from the principle thereof.

What I claim is:

1. In a goggle, the combination of a dished rubber pad having eye openings, a iiange on the pad about each eye opening, metal retaining rings formed half-round in cross-section, the flat surface of each ring being adapted to engage the ange surrounding one of said eye openings, means for securing the pad ilanges and rings together, and a pair of metal frames, each adapted to carry a lens and each formed with an interior groove having a curved Wall adapted to receive the curved surface of one of the retaining rings.

2. In a goggle, the combination of a dished rubber pad having eye openings, a retaining ring for each eye opening, means for securing the retaining rings around the eye openings, a pair of metal frames with an interior groove to receive one of the retaining rings, said metal frames being split transversely to provide openings therein, pairs of Wings on the frames, one at each side of the frame openings, and slides having channels adapted to receive and slide on said Wings to open or close the frames to permit of the removal or insertion of the retaining rings on the pad.

3. In a goggle, the combination of a dished rubber pad having eye openings, a retaining ring for each eye opening, means for securing the retaining ring around the eye openings, a pair of metal frames each formed with an interior groove to receive one of the retaining rings, said metal frames being split transversely to provide openings therein, pairs of Wings on the frames, said Wings being formed by reversely bending the edges of the frames at said openings, and taped slides mounted on the frames, the edges along each side of the slides being turned under to form channels adapted to receive and slide on the Wings to open or close the frames to permit of the removal or insertion of the retaining rings on the pad.

4. In a goggle, the combination of a dished rubber pad having eye openings, a retaining ring for each eye opening, means for securing the retaining rings around the eye openings, a pair of metal frames each formed with an interior groove to receive one of the retaining rings, said metal frame being split transversely to provide openings therein, pairs of Wings on the frames, said Wings being formed by reversely bending the edges of the frames at said openings, perforated ears on the frame at each side of said openings, and slides mounted on the frames, said slides having channels adapted to receive and slide on said Wings, one end of said slides being formed with a perforated nose adapted to t over the perforated ears of said frames, the perforations in said nose and in said ears being in alignment CHARLES FISCHER.
